It has been 10 years since the last review on apomixis, or asexual seed formation, in this
journal (Koltunow, 1993). In that article, emphasis was given to the commonalties known …

Genetic studies of embryo, ovule and flower development in Arabidopsis thaliana have led
to the independent isolation of different mutant alleles of a single gene (SIN1/SUS1/CAF …

The 21-nucleotide small temporal RNA (stRNA) let-7 regulates developmental timing in
Caenorhabditis elegans and probably in other bilateral animals. We present in vivo and in …

MicroRNAs (miRNAs) are an extensive class of∼ 22-nucleotide noncoding RNAs thought to
regulate gene expression in metazoans. We find that miRNAs are also present in plants …

We predict regulatory targets for 14 Arabidopsis microRNAs (miRNAs) by identifying mRNAs
with near complementarity. Complementary sites within predicted targets are conserved in …

The molecular basis for virus-induced disease in plants has been a long-standing mystery.
Infection of Arabidopsis by Turnip mosaic virus (TuMV) induces a number of developmental …

Dicer is a multi‐domain RNase III‐related endonuclease responsible for processing double‐
stranded RNA (dsRNA) to small interfering RNAs (siRNAs) during a process of RNA …

The gametophytic maternal effect mutant medea (mea) shows aberrant growth regulation
during embryogenesis in Arabidopsis thaliana. Embryos derived from mea eggs grow …

The angiosperm seed is composed of three genetically distinct tissues: the diploid embryo
that originates from the fertilized egg cell, the triploid endosperm that is produced from the …

Early in their evolution, plants acquired a life cycle that alternates between a multicellular
haploid organism, the gametophyte, and a multicellular diploid organism, the sporophyte …
